如何在我的编码 android studio 项目中实现此代码 setDisplayName？

Question

我想将 setDisplayName() 实现到我的代码中，但不确定如何执行。我应该将 setDisplayName 放在代码中的什么位置？我想在导航栏标题中显示客户名称。

这是我的代码

//create customer

firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(RegisterActivity.this, new OnCompleteListener < AuthResult > () {

    @Override

    public void onComplete(@NonNull Task < AuthResult > task) {

        if (task.isSuccessful()) {

            Customer info = new Customer(name, email, address, number, gender);

            FirebaseDatabase.getInstance().getReference("Customer")

                .child(Objects.requireNonNull(FirebaseAuth.getInstance().getCurrentUser()).getUid())

                .setValue(info).addOnCompleteListener(new OnCompleteListener < Void > () {

                    @Override

                    public void onComplete(@NonNull Task < Void > task) {

                        regProgressBar.setVisibility(View.VISIBLE);

                        Toast.makeText(RegisterActivity.this, "Registration Complete", Toast.LENGTH_SHORT).show();

                        startActivity(new Intent(getApplicationContext(), Home.class));

                    }

                });

        }

    }

});

代码流程如下：用户使用电子邮件和密码注册。然后使用 FirebaseAuth 设置用户显示名称UserProfileChangeRequest。顺利完成后。您的数据将保存在数据库中mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {&nbsp; &nbsp; @Override&nbsp; &nbsp; public void onComplete(@NonNull Task<AuthResult> task) {&nbsp; &nbsp; &nbsp; &nbsp; if(task.isSuccessful()){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Sign in is successful&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .setDisplayName(name).build();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; user.updateProfile(profileUpdates)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .addOnCompleteListener(new OnCompleteListener<Void>() {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @Override&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void onComplete(@NonNull Task<Void> task) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (task.isSuccessful()) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Customer info = new Customer(name, email, address, number, gender);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; FirebaseDatabase.getInstance().getReference("Customer")&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .child(Objects.requireNonNull(FirebaseAuth.getInstance().getCurrentUser()).getUid())&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .setValue(info).addOnCompleteListener(new OnCompleteListener < Void > () {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @Override&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void onComplete(@NonNull Task < Void > task) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; regProgressBar.setVisibility(View.VISIBLE);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Toast.makeText(RegisterActivity.this, "Registration Complete", Toast.LENGTH_SHORT).show();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; startActivity(new Intent(getApplicationContext(), Home.class));&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; });}
